Abstract
A case of sarcomatoid transitional cell carcinoma of the renal pelvis is reported. It was distinguished from carcinosarcoma by immunohistochemical study. The tumor was difficult to distinguish from a renal parenchymal tumor in imaging studies because it originated from a duplicated renal pelvis.
